"i To all wliomt mag/concern;

`Bc it known that I, JOHN GIBBONS, of West a Troy, in the county of `Albany and State of` New Yo1'k,have invented certain new and usefu lslful Iniprovementsin Snap-Hooks, of which.

l `tlielfollowing is a full and exact description,

l :rei'erence beinghadtotheaccompanying draw- 1 `gings, which form part of this sperih'cation, and

:in which-7- A i Fig.,2, a `longitudinal section of the same;

` land is provided at one end with aAhook, a, l which, for the purpose of facilitating the oper- 3o` ation of molding it for casting and for `the l insertion of the otherparts ot' theAdevice, should, when irst produced, have a sidewise l twist in it, as shownin Fig. 3. At its oppo-` site end the bodyfpiece has an eye, a', or othenA islaI side elevation of my invention A of `the"device,`andAFig. 4a plan `View ofthe The` body-piece Ais ca st otxnalleable metal,

which engages under .the end of thehook a and closes the opening at that point. The said 45 wing prevents the sliding bolt fromturning in the chamber a2, and thus maintains the rear- Wardly-projecting'lip b in an accessible position for receiving the pressure from a ngerl or thumb when it is required-,to force the said bolt downward in the chamber a2; l

The spring C is contained in the chamber` a2, and is arranged to exert its pressurea-gai ust the lower end of" the sliding bolt B in such manner thai-,the head of said bon win be heid 55 A l in contact with the under side. of the end ot' thehook a;

AToopen this snap-hook the sliding bolt B must be pressed downward into the'chamber a2 until lsufficient space is obtained between 6o the `head of said bolt and the end of the` hook a for the introduction of any required article l thereinto. rlhen, upon the releasement ofthe downwardlpressure, the resilient force of the spring C will cause the' sliding bolttoreturn 65 to its position of contactwith the hook l y AWhen preferredl the wing b `and lip in', or` either of them, may be dispensed with;` but in such cases the cylindrical head ofthe sliding bolt B should be adapted to engagenndenthe 7o end, of the hooka.

' I- claim` as my inventionl A In a snap-hook, the combination, with abodypiece, A, provided with a hook, a, anda chamber, a2, the latter 4being ranged crosswise ot' 75 the longitudinal center line of said body-piece,

as herein described, of the sliding bolt Band spring G, contained in the chamber a2, the said sliding bolt being arranged to move crosswise of the center line of the body-piece A, and to 8o engage against the under side of the end of hook a, as and for the purpose specified.
